'1 Claim. (01. 292-167) them from swinging open when they are closed.

Another object is to provide a device adapted for inside use for holdingdoors of offices and homes.

I am aware of the fact that door-holding devices have been used whichare placed in operative position by pressure of the foot. Asdistinguished from such devices, another object of my invention is toprovide a device which when released will-automatically move intooperative position for holding the door.

The full objects and advantages of my, invention will appear inconnection with the detailed description thereof, and the novel featuresof my inventive idea will be particularly pointed outin the claim.

;,In the accompanying drawings, which illustrate some of the forms inwhich my invention may be embodied, 1

Fig. 1 is an elevational view showing my device applied to a pair ofgarage doors. Fig. 2 is a View in section on the line 22 of Fig. 1, onan enlarged scale. Fig 3 is an elevational view of a door held I in openposition. Fig. 4 is a fragmentary view showing a slight modification.Fig 5 is a view in section on the line 5-5 of Fig. 4 on an enlargedscale. Fig. 6 is an elevational view of a modified construction. Fig. '7is a view in section on the line 7-7 of Fig. 6 Fig. 8 is a fragmentaryView of a still further modification. Fig. 9' is a side view of a slightmodification of the form shown in Figs. 4 and 5. Fig. 9 is a verticalsectional view of another form. Fig. 10 is a partial face view of thisform. Fig. 11 is a vertical sectional view of a still further form. Fig.12 is a partial face view of this last form. I Referring to theconstruction illustrated in th drawings, and-first more particularly tothe form shown in Figs. 1, 2 and 3, a pair of garage doors 10 and 10 areshown in closed position in Fig. 1. One of my devices is shown appliedto each of these doors. In constructing this form of the device Iprovide a rod 12 which at one end is bent atright The rod means of twostaples 16 through which the rod is adapted'to slide. The staples aredriven into the door in proper position toward the bottom thereof.

A nail 18 or similar device is driven into the door in proper positionto form a rest or stop adapted to be engaged by the handle 14 to holdthe rod 12 suffici ntly elevated so as not to engage the floor orground. .A. second nail 20 or similar device which constitutes ananchoring element is driven into the door in such position that a coiledspring NT oFFicET 22 when attached at one end to this nail and attachedat the other end to the handle 14 will be stretched so as to be placedunder tension. Fig. 3 shows the door 10 in open position, the handle 14having been turned to release it from the rest or stop 18. The tensionof thespring' 22 causes the rod 12 to move'downwardly so that its lowerend will engage the floor or ground and thereby firmly hold the door inthe desired position.

Figs. 4 and 5 show a slightly modified form of the device applied to'adoor 24 for use in an oflice or a home. In this case the staples 16, arere placed by bearings126- secured .to the door by screws 28 so thattherod 12 may slide through the bearings. This form of the device isotherwise similar to that already described except that v a rubber tip80.is placed on the lower end of the rod 12 for engaging with the floor.

Figs. 6 and 7'show another formof the device which is. particularlyadapted for application to new'doors, such as door 32. In this" form ofthe device a vertical opening 34 is made in the door extending from thebottom thereof upwardly for a proper distance. of this opening a smallpanel is out out of one side of the door so as to leave a cutaway area36 through which the rod 12 is inserted downwardly through the opening34. A guide 38 for the rod is then placed in the opening 3% and thelower. end of the rod is provided with a' rubber tip 30. A plate 40 issecured over the cut-out area'36 by screws or other fasteners 42. Thisplate has a bayonet slot 44, the upper portion of 'whicliis adapted toform arest for the angular member 14 carried by the upper end of the'rod12. The lower inner surface of the plate 36 carries a projection 46which constitutes an anchoring element for attachment of the lower endof the a in use. Fig 9' shows a form similar tothat of fie Adjacenttheupper portion its Figs. 4' and 5, the difference being that a plate25 is secured to the door and the ends of this plate are turned out atright angles to provide bearings 26' in which the rod 12 slides.

Figs. 9 and 10 show another form of the device in which acompressionspring and a holding dog are used in connection with a door 50. In thisform a vertical opening 52'is made in the door extending from the bottomthereof upwardly for the proper distance. The upper portion of thisopening is made smaller than the lower portion to provide a shoulderagainst which a ring 54 rests. Adjacent the upper end of this opening,one side of the door is cut away to provide a circular opening 56, themargin of which is rabbetted to receive a circular plate 58 held inplace by screws 60. A shaft member 62 extends through the plate 58, theouter end of this member 62 being provided with a handle 64. Within theopening 56 the shaft 62 carries a. disc 66 and a barrel 68. Theperiphery of the disc 66 is provided with a notch 70 in which the innerend of a dog 72 is adapted to engage. This dog is mounted on a pivot 74held in the opening formed in the upper portion of the plate 58. Theouter end of the dog on its upper surface is knurled, as indicated at 76in Fig. 1G in order that the dog may be readily engaged by the operator.A wire cable '78 is adapted to wind on the drum 68, the upper end ofthis cable being secured to the drum while the lower end thereof issecured to the upper end of a rod 86 which passes slidably through thering 54. The lower portion of the rod 80 is formed with an enlargement82. A compression spring 84' surrounding the rod 80 is interposedbetween the enlargement 82 and the ring 54. The enlargement 82 isadapted to'sli'de in a bearing 86 secured at the lower end of theopening 52. The enlargement 82 at its lower end carries a rubber tip 88.In Fig. 9, the dog '72 is shown in released condition in full lines, sothat the compression spring 84 acts to hold the rod 80' downwardly withthe rubber tip 88 engaged with the floor. In order to place the devicebut" of operative position, the handle 64 is turned and the dog '72 ismoved into engagement with the notch 70. When the outer end of the dog'72 is pushed downwardly the, spring 8% acts instantaneously to lowerthe rod 80.

In the form shown in Figs. 11 and 12', the door.

90 is provided with a vertical opening 92 which extends from the bottomthereof upwardly for the proper distance. Adjacent the upper portion ofthis opening a small panel is cut out of one side of the door so as toleave a cut-away area 94 which is covered by a plate 96 secured in placeby screws 98. A shaft member 100 extends through plate 96, the outer endof this shaft being provided with a wing member 102 for turning theshaft. The inner end of the shaft 100 carries a crank 104. A projection106 extends out laterally from the crank 104. This projection extendsthrough an opening in the upper end of a connecting rod 108 whose lowerend is attached by a 'pivotlIO to the upper end of a rod 112. The lowerportion: of the rod 112 is formed with an enlargement 114 adapted toslide in a bearing 116 secured at the lower end of the opening 92. Theenlargement 114 at its lower end carries a rubber tip 113. The lowerinner surface of the plate 96 carries a' projection 120 whichconstitutesan anchoring element for attachment of the lower end of aspring 122 whose upper end is attached to the projection 106 whereby thespring is placed under tension. Fig. 12 shows the wing member 102 turnedto bring the crank 104 upwardly so that the rod 112 is held out ofoperative position.

Upon giving the wing member 102 a slight turn the spring 122 wi ll forcethe rod 112 downwardly I for engagement with the floor.

I claim:

A door-holding device comprising a rod mounted for vertical slidingmovement in an opening at the lower end of a door, said door on one ofits sideshaving a cut-out area at the upper end of saidopening, a platesecured over said outout area, a shaft passing through said plate, a

handle member on the outer end of said shaft, a

said projection whereby the lower end of said rod iscaused to engage thefloor whensaid crank'arm is turned from upper toward lower position.
